Help needed quickly.....

[DsrtJeeper]

OK; here it is. I've been suffering bad driveline vibes and I narrowed it down to my front driveshaft. My Son remembered I had the front slip yoke apart and I was wondering if there are marks on the female yoke half to match to the male, splined shaft? I know my rear is reference marked for balancing purposes, so is the front too? I see what appears to be a punch mark on the very end of front male shaft. I can't find any marks on the female yoke. Please help! I'm headed to Moab tomarrow.

Thanks to Troy today for his gracious help also!

from what driveshaft shops have told me, ujoints must line up with each other

[DsrtJeeper]

Yeah; I heard that also and tried it this way and 180* the other way. Both ways vibrate. I think my shaft may be bent. Thanks!

assuming you have CV drive shaft, having put lift on you need to adjust castor ... point pinion yoke at transfer case
unfortuneatly, if you change too much you could experience "death wobble"
there is cam on lower control arm to make small adjustments
